This game is all-around excellent. The visual effect seem to transcend the Pico-8. I also enjoyed a lot listening to the track "don't look at me (again)". In fact, I would simply put up the game and let the game run by itself while I listen to the song.
Of course, I have yet to finish the 1st level. (hahaha)

I am twice thankful for your writing your notes on programming on the Pico-8, especially on your notes on how to properly do collision-detection. I was unaware at how bad the standard form of collision detection was. I hope that your algorithm of collision-detection gets more popularity.

I also appreciate a lot your version of the cartridge that had all of the comments.

Like I wrote, I'm still not even sure what "standard" collision detection could possibly be without having several glaring artifacts.

Also, I advise against copy/pasting the collision detection into your own project — I found a couple bugs in it when I set about using it in a second game, and of course it's not particularly speedy. Hopefully it'll be usable by the time that second game is done. :)

That was great! It has a very unique look, and the sounds were fantastic. The controls were tuned really well so that it felt good to move around the world. Solving multiple puzzles within the same space was a brilliant way to work within PICO-8's constraints! The credits were a nice touch as well. It's a very complete experience, thematically and gameplay-wise. Definitely one of my favorite games I've played on here.

What a fantastic comment, thank you so much from both of us! I'm pretty fond of the credits, one of the two parts that were entirely my responsibility. :) And I'm fairly picky about platformer physics, so I'm glad you liked mine!

You know, I found this game over 6 months ago, and it's still remained possibly my all-time favorite PICO-8 game. It's such a bizarre, surreal world to explore, the different "acts" make great use of the map and really encourage you to learn your way around the space, the soundtrack is quite interesting and fitting, and the limited palette gives it a rather distinct look. I love the way you get to see your character's thoughts each time you fail or restart, and Mister5 is such a bizarre entity to interact with.

In some ways, Under Construction was even an inspiration for one of my own games, NULL, at the very least by virtue of proving that you can make some truly unusual, even surreal games on this platform.

Haven't found a single thing about this game other than by the creator n' stuff, and it took me days figuring out what to do but i've finally finished. Love this game, and I've uploaded a video of my completing it, since there's no videos or anything about it. :p

Just found this game. Wow! I really love the "don't look at me (again)" track, which is a good thing, because I spent a lot of time jumping around that level. I'm not sure I know what I'm doing. But the art and music is great, and the physics feel really smooth.
